One possible plotline could be Naruto's struggle to adapt to his new disability. He might have to relearn his ninja skills, like how to fight and perform jutsus with only one arm.

A third plotline could be centered around Naruto's search for a way to regain his arm. He could embark on a dangerous quest to find a powerful healer or a magical artifact that could restore his limb. Along the way, he would face numerous challenges and enemies, all while dealing with the limitations of having only one arm.

One possible plot development could be Naruto having to relearn his ninja skills with only one arm. He might struggle at first, but then discover new ways to use his remaining arm in combination with his chakra control. For example, he could focus more on using his legs for powerful kicks and use his one arm mainly for balance and quick jabs of kunai or shuriken. Another aspect could be the psychological impact. Naruto might feel a sense of loss and inadequacy, which could lead to some self - discovery as he overcomes these feelings and becomes stronger in the end.

One possible plotline could be that Harry loses Malfoy in a dangerous magical maze. Maybe they were on a joint mission for some reason, like to retrieve a powerful magical artifact.

Maybe there's a prophecy that says something bad will happen to one of them if they stay friends. But Mal and Evie don't care about the prophecy. They fight against the forces that try to keep them apart, whether it's a magical curse or a group of people who oppose their friendship. Their loyalty to each other is unwavering.
The plot could also involve a time - related crisis. Maybe something is threatening the timeline, and the only way to fix it is for future Naruto to raise his younger self in a certain way. So, future Naruto has to make sure that the younger Naruto grows up to be strong enough to face this threat while also maintaining the integrity of the timeline.
One possible plotline could be that Naruto somehow ends up in Akeno's world. They meet and at first Akeno is a bit shy around Naruto. Naruto, with his positive attitude, gradually befriends her. They could go on adventures together, like facing some common enemies in Akeno's realm. Naruto's ninja skills would be very useful in such situations.
